You can get a modest degree of obscurity by distributing the .pyc
bytecode files instead of the .py source. These can still be decompiled
and reverse engineered but it is more effort.
I suppose you could rewrite some or all of the code into the Python
dialect supported by Pyrex and compile it that way.
Pyrex is "a language specially designed for writing Python extension
modules." The docs say "Almost any piece of Python code is also valid
Pyrex code." So it might not be too hard to compile your Python source
into an extension module using Pyrex.
